LT3483AIDC

Overview

The LT3483AIDC is an inverting micropower DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5 V to 16 V and delivers a negative output voltage up to -38 V at a maximum current of 200 mA. The device features a low quiescent current of 40 uA and a fixed switching frequency of 150 kHz. It is housed in a TSOT-23-6 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

Inverting topology for generating negative supply rails from positive inputs
Micropower operation with low quiescent current consumption
Integrated Schottky rectifier for improved efficiency
Compact TSOT-23-6 surface-mount packaging

Applications

Battery-powered systems requiring negative bias voltages
Portable instrumentation with limited power budgets
Sensor interfaces needing dual polarity supplies
Communication modules utilizing RS-485 transceivers

Procurement Notes

Verify the specific suffix 'IDC' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with the required input voltage range and load current specifications before integration. Cross-reference the datasheet revision to validate electrical characteristics and pinout assignments for the final design implementation.

Selection Notes

Select this component when a compact solution is needed to generate negative voltages from single positive sources. It is suitable for applications prioritizing low standby current and minimal footprint. Consider the 150 kHz switching frequency for EMI constraints and ensure the external components support the required output current capability.

Part Context

The LT3483 series belongs to Analog Devices' portfolio of micropower switching regulators. This family focuses on energy-efficient power management for portable electronics. The LT3483A variant typically offers enhanced performance or tighter tolerances compared to standard versions, maintaining the core inverting converter functionality within a small form factor.
